SYSML11 — Chapter Blocks/Section 8.3.2.6

I am trying to support PropertySpecificType in our SysML Toolkit and I hit some road block while trying to implement the same. I have had some discussion with Sandy last week regarding the same but I quiet don’t get how this can be supported without some additional constructs to the PropertySpecificType stereotype. Below are the lists of questions I have: When a default value is provided for the property type, then a type derived from the original type should be created and its default value should be set as the new deafult value of the property. The property type should be displayed in square brackets which would indicated that the type is a specialized type. There can be more than one specialization of the same class, in such case there is no construct to store which specialization is associated with which property? This additional construct is very much needed because there is no way to know whether the specialization is created by SysML for PropertySpecificType or whether it is created by user? What happens in case of multi-level hierarchy? (If Class2 inherits Class1, and property1 is typed by Class2 & the default value at property1 is changed the resultant propertyspecifictype is Class3. Should the tool show property1:[Class2] or property1:[Class1]). Why is the PropertySpecificType extends UML2::Classifier and not UML2:Type? PropertySpecificType was introduced to provide specific default values to properties in Internal Block Diagram. Why not use the InstanceSpecification from UML2? Below Diagram shows how this is supported in UML2.
